MDLS-40466-SS-HV-S-LED-04-G Application Field and Working Principle

MDLS-40466-SS-HV-S-LED-04-G, part of the LCD, OLED Character and Numeric display modules, is a 4-digit, seven-segment LED display module with excellent performance and reliability.

The module consists of a 4-digit LED display, a green LED driver IC, a resistor network and a logic array IC. It has a built-in self-test feature which ensures the display functions properly. The display module also has a unique self-needless feature, which is ideal for applications requiring little effort when setting up the display.

It can display 4 digits of numbers, letters and symbols and works on common anode type for low power. The module can also be used in various applications such as measuring systems, digital system displays, displays for the radio and main panel, instrument and meters display, vehicle display and so on.

Application Field

MDLS-40466-SS-HV-S-LED-04-G is mainly used in measuring systems, radio and main panel display, vehicles display and digital system displays.

• Measuring Systems – the module is used in the measuring systems to display parameters such as temperature, humidity, pressure, current and voltage.
• Radio and Main Panel Display – the module is used in the radio and main panel display to provide information such as station frequency, signal strength and signal type.
• Vehicles Display – the module is used in vehicles display to show various related information such as speed, mileage and remaining gas.
• Digital System Displays – the module is used in digital system displays to provide functional status such as detection and fault indication.

Working Principle

MDLS-40466-SS-HV-S-LED-04-G LED display consists of four digitally controlled LED pins. When a pin is turned on or off, the LED display will produce different numbers, letters and symbols. The pin outputs are connected to an LED driver chip which is controlled by a logic array IC.

The logic array IC controls the LED driver chip in order to display a 4 digit numerical output. The input to the logic array IC is either a digital or analog signal, which is used to produce the desired output. When the logic array IC receives the input signal, it scans the data and sends the required signals to the LED driver chip.

The LED driver chip receives signals from the logic array IC and sends them to the LED pins. The LED driver chip is also responsible for providing various current levels to the LED pins depending on the type of display desired. This allows the module to display different digits, letters and symbols at various brightness levels.

The module also has a built-in resistor network which is used to limit the current flow to the LEDs to produce stable output at all brightness levels. The resistor network also offers protection from overloading the LEDs, which can cause damage to the module.

MDLS-40466-SS-HV-S-LED-04-G is a reliable 4 digit LED display module which offers great performance at low cost. It is perfect for applications requiring simple set up and easy maintenance.
